Abstract

Hall-effect sensor of the type with two-dimensional electron gas and comprising, on an insulating substrate (10), a quantum well structure (12), a carrier-yielding layer (20) adjacent to the quantum well structure (12), less than 250 angstroms thick and having a surface density of donors, when integrated through the whole thickness of the carrier-yielding layer, of less than 5 10<12>cm<-2>, an insulating disposal layer (22) deposited on the carrier-yielding layer, having a conduction band of energy greater than the Fermi energy of the sensor and greater than 200 angstroms thick. Application to the field of electrical counters and current sensors. <IMAGE>
